Hello Yall,
I have the following ignition coil...Currently the engine cranks strong, but will not start. I put a test light on both sides of the plug as seen below, and both sides lit RED...I'm assuming the green w/yellow stripe is ground, and the Red w/dark blue stripe is positive

Note:
The test light I have will light up green if testing ground connection, and red when testing hot connections

Questions:
The two green wires, where should they go on the other end?

I'm definitely not getting spark. I have a brand new coil, ignition module, distributor, cap & rotor, new ignition switch and a new alternator and a fully charged battery

I would really appreciate your help with this...I have been struggling with this issue for 6 months now

I even got a mobile mechanic to come out. He managed to start the engine for about 5 minutes, but the coil was getting way too hot, then the engine died, and I have not been able to start it again (I swapped the ignition coil since then)

Another question:
I have a Motorcraft distributor with the adapter. The distributor cap has #1 marked on one of the ports. Does that mean once TDC is set I can plug Park plug #1 to the port labeled #1 and just follow the firing order, in other words, does it matter where I plug Spark plug #1 wire as long as I follow the firing order?

Actually, this is on a 1978 Jeep CJ-7 with an AMC 304 V8 engine that uses this coil found on mustangs from 1983-1995
